This study introduces a novel wearable electrocardiogram (ECG) system for monitoring anesthesia depth. It achieves high accuracy, offering a cost-effective alternative to traditional electroencephalogram (EEG) methods.

Area of Science:

  • Biomedical Engineering
  • Anesthesiology
  • Artificial Intelligence

Background:

  • Traditional anesthesia depth monitoring relies on electroencephalogram (EEG)-based indices like Bispectral Index (BIS), requiring specialized equipment.
  • Electrocardiogram (ECG) signals are readily available, wearable-compatible, and sensitive to anesthetic agents.

Purpose of the Study:

  • To develop a wearable ECG-based framework for accurate depth-of-anesthesia detection.
  • To leverage autonomic nervous system characteristics and knowledge graph-enhanced graph convolutional networks (GCNs).

Main Methods:

  • ECG recordings from 110 patients were analyzed, extracting 20 anesthesia-related features.
  • Feature selection identified 13 discriminative features.
  • A patient-level knowledge graph was constructed and utilized with a GCN for inductive inference.
